doc_holliday··on Ask HN: Effect of Brexit on DEV Jobs in UK?
"We might hit a +10% on food price (and gaz) in a near future. It might get harsh[er] for big families and low income jobs, it's fine for people with good salaries."

However, those people with good salaries whilst seeing inflation running at 10% will likely not see a wage increase to match. And they may also have just bought a house...

At the same time as 10% inflation, the BoE may eventually have to raise interest rates to try curb capital flight from Sterling and make it attractive again.

Higher interest rates & stagnant wages lead to people not being able to keep up with mortgage payments (which have just increased and so has everything else but their wage).

This leads to defaults on mortgages at the same time as house prices are falling because people cannot service such large mortgages at 10% interest.

That will hurt a lot of people with good salaries in the short term.

doc_holliday··on Ask HN: Effect of Brexit on DEV Jobs in UK?
"(~20% cut to GBPUSD, 1% inflation...)"

IMO we are about to hit much more than 1% inflation with the devaluation of our currency.

Think how much petrol has gone up, food is about to go up, imports are going up etc.

We will have much more than 1% inflation annually next year I think, and I don't think wages will keep up. That is if things go ahead as they currently are.

On the flipside this makes Devs in the UK much cheaper, and if we have the combination of inflation and stagnant wages then the housing market will collapse, which will eventually make UK more competitive.

doc_holliday··on The surprising benefits of a mid-career break
That is all fine and well during a property bull cycle (which admittedly we've had for the last decade plus in the UK).

But equally property really ties you down if you are dependent on paying a mortgage. If you live somewhere with not huge demand for rental, then you cannot leave your job.

Mortgages and property prevent many people from taking time off, I could tell you of loads of people I know who cannot take time off because they need their monthly wage for mortgage.

doc_holliday··on Barack Obama: America Will Take the Giant Leap to Mars
It'd be really interesting to see the economic comparisons of both against each other.

I.e the cost per kg of payload shipping from America to Europe in 17th Century vs the cost per kg of payload shipping from Mars to the Earth in 21st Century.

I suspect the Mars in current day is much greater, but ships and crew back then were not cheap.

doc_holliday··on Why a Brit chose to start a business in Berlin
Oh, you'll meet loads of great people and it is an experience getting out of your comfort zone and leaving behind old friends in the city you grew up in.

I was just meaning in regards to differing opinions to liberal metropolitanism it will be very similar to London. Best of luck in your endeavour!

doc_holliday··on Why a Brit chose to start a business in Berlin
"My business is called The Echo Chamber Club — we curate articles that counter a traditional metropolitan viewpoint and send them to our hundreds of subscribers. It makes sense that I remove myself from London to understand new points of view and communicate them with my subscribers."

With regards to "liberal metropolitan" viewpoints, Berlin won't challenge you anymore than London did. It's just another global city where inside your group of people you are likely to meet (given what you work in) they will more than likely be liberal and metroplitan.

doc_holliday··on Tabs or spaces – Parsing a 1B files among 14 programming languages
Lots of people need to access files on a server via Emacs or Vim. Having to deal with tabs there can be very frustrating.
doc_holliday··on FPGAs and Deep Machine Learning
It's possible that if FPGAs continue to improve as they are and catch up with ASICs in terms of density and price then reconfigurable HW may become a possibility.

At the moment, most of those task would be done on ASIC, so yes we might see those tasks done on FPGA.

There wouldn't be advantage in performance generally, only in that you could have true HW updates.

It is something I've been thinking about in that you could theoretically have a processor optimized for the game. So you could download HW on the fly (pre built) and flash your machines FPGA.

doc_holliday··on FPGAs and Deep Machine Learning
Unlikely for many years (if ever), compiling HDL down to an image to flash FPGA with takes hours. Routing wires etc is very difficult process and is very compute intensive.

JIT for FPGA is quite possibly mathematically impossible.

doc_holliday··on FPGAs and Deep Machine Learning
It's excellent to see FPGAs being increasingly utilised.

As moore's law no longer holds true for CPU, there is increasing interest turning to FPGAs. You can create a truly bespoke Processor for any task.

Of course this is trade of between development time / cost vs processing needs of task.

I suspect FPGAs demand to only increse over the coming years. Intel's integration of FPGA into their line of processors is a promising step and sign of where things may be heading.

doc_holliday··on How to be mediocre and be happy with yourself
It's absolutely important to your well-being and happyness to understand when something is enough and to be at ease with what you have.

Hedonistic tendancies teaches you to want more and more, you never appreciate what you have because once you have got it you want the next thing. It becomes a zero sum game and you've probably just sacrificed a whole heap of your precious time and health to achieve it.

Many people fall trap to trying to beat others in what they have / what they do.

They see their friend has a bigger house, they want a bigger house.

They see their friend had a big weddding, they want a bigger wedding.

They see their friend earns X a year, they want to earn X + Y a year.

Remember, there are 7 billion people on the planet, you will probably not be the richest ever, so learn to be happy with what you have.

This is not to say do not strive for improvement, just allow yourself to be happy.

doc_holliday··on Age differences in learning from an insufficient representation of uncertainty
I think sometimes bravado of knowledge can play into this. People as they become adults like to think they are very knowledgeable and don't want to come across as "stupid".

This means most adults will never ask the simple questions and pretend like they understand something complex quickly or already know. It's a dangerous mindset to develop but it's difficult not to.

As most on here are programmers how many times have you been in a meeting or technical discussion where you are judged for asking a "simple" question?

We need to stop the judgement of those that ask "simple" questions.

doc_holliday··on Ask HN: How have you achieved financial independence?
Related, I am wondering if any of you have any tips on securing financial independence / passive income that will hopefully be Tech recession proof.

I.e, best way to see yourself through a Tech downturn without taking a severe hit to your wealth.

I say this because I've had recent experience with people losing huge amounts of their wealth, and almost going bankrupt during the Oil price crash.

For instance I know Oil workers who had most of their wealth in oil company shares, a house in an oil related city and lose their oil industry job.

I'd imagine their are lots in tech that are the same, large amount of Tech shares, a house in the Bay area and a job in Tech.

Anyone got any tips on diversifying for a downturn? What shares (if any???) are likely to do well if Tech has a bad patch.

doc_holliday··on Ask HN: Know a good tool to purge all posts/likes/photos from Facebook?
Not sure how possible it is, but i've used Javascript from the web console to do some interaction with Facebook, perhaps they have restricted this though?

But if that is allowed that could be one route, getting all the elements by Xpath that are posts.

Otherwise automation with Selenium or similar could work?

doc_holliday··on Foreign residential property buyers to be taxed at 15% in Vancouver
Well because the property is extremely overpriced when you consider market rate rents the yields are extremely low. You can only charge as much rent as the market will bear, which in some ways makes rental completely different to ownership prices.

Basically the people buying it don't deam the return on renting it worth the risk of a bad tenant or worth the hassle.

They don't need cashflow, are either using it as a safe holding of value or as a quick escape property if they need to leave insert country here for political reasons.

It's happening the world over.

doc_holliday··on MIT and DARPA Pack Lidar Sensor onto Single Chip
The application of these light phased arrays to Holography and the making of a truly Holographic display with reasonable resolution is very exciting.

This is to Holographic displays as LEDs was to standard displays.

doc_holliday··on Donkey – A computer game included with early versions of PC DOS
Yes! TI Basic on my Texas Instruments graphics calculator was how I spent downtime during math class.

So much so, I remember writing program for solving quadratic equations.

They were supposed to clear the calculators memory during exmas, but the exam invigilators had no idea what calculators could do, so they didn't.

I'd like to think it wasn't cheating... as writing quadratic solver in TI basic is harder than solving simple quadratic equations. And I did do them all by hand anyway in the exams...

doc_holliday··on No grades, no timetable: Berlin school turns teaching upside down
"eight-hour Scrum meeting"

Why are you having an eight hour Scrum meeting?

Isn't that the complete opposite of what a Scrum meeting is supposed to be? 15 minute max, standup meeting is a Scrum.

doc_holliday··on After ‘Brexit,’ Finding a New London for the Financial World to Call Home
By law they have to do no such thing.

It's a a very tender point with people because people get weirdly patriotic regarding Scottish Pound Notes. But they are a sort of bizzare currency.

Scottish notes are a legal currency, but not a legal tender. In fact there is no such thing as legal tender in Scotland. Even BoE notes are not legal tender in Scotland.

Legal tender only means you can legally pay down debts by court order in the given currency. BoE notes fulfill this job, but only in England & Wales.

"Someone told me that, by law, they have to accept those notes"

No, they don't even have to by law accept BoE notes in England. Only for paying down debts by law is that true.

Any shop or whatever can refuse or accept anything you give them.

However, to add further confusion, every single pound of Scottish notes is backed up by BoE pound sterling.

In the banks that print Scottish notes (Clydedale, RBS, Bank of Scotland) they have to keep an equal ammount of BoE Sterling.

They even created special notes so they could hold the currency in their vaults in Banks.

You can get £1,000,000 and £100,000,000 notes called Giants and Titans, which back up the Scottish and NI pound notes.

What you are legally entitled to do however (I think?) is go into any branch of Bank you have a Scottish note of and request the equal in BoE note.

So if you have £20 RBS Scottish note, you can go in to an RBS branch legally and claim your BoE note with a nice picture of Adam Smith on it :)

doc_holliday··on HardCaml: Register Transfer Level Hardware Design in OCaml
Here are some module design equivalents: http://www.ujamjar.com/hardcaml/chisel.html

As far as performance of what it synthesises down to, I have no idea as I have used neither.

Are you complete newbie to HDL?

doc_holliday··on Ootside – Weather from a brutally honest Scottish perspective
I see that now after hitting refresh!
doc_holliday··on Ootside – Weather from a brutally honest Scottish perspective
Usually the case...

But it is a rare day up North!

Affa bonnie.

doc_holliday··on Ootside – Weather from a brutally honest Scottish perspective
I think some of the definitions need to be worked on... what looks like overcast weather is described as "Dreich".

That's not what dreich is! Dreich would involve lots of clouds, rain, drizzle and just all round miserableness.

doc_holliday··on Open Source Speech Recognition
Do you have link to good emotion recognition if you have used one?

Perhaps, could use wrapper library to combine functionality. It's a very interesting area.

doc_holliday··on Open Source Speech Recognition
Slightly related, does anyone know of any speech recognition library that also analysises the intonation / emotion in speech?

For example that has the ability to recognise anger / happy / questioning to relative accuracy?

doc_holliday··on Ask HN: Tabs or Spaces?
And to add... there is no excuse not to use spaces even if you like the tab key.

Configuring your favourite text editor to interpret a tab key press as 2, 4 or whatever number of spaces for your project is trivial.

doc_holliday··on Ask HN: Tabs or Spaces?
Spaces of course.

Tabs can be messy across version control and multiple users with differing OS / editor.

doc_holliday··on FPGA Webserver
ASICs aren't necessarily faster these days. Some of that clock speed comes down to floor planning, which takes a lot of design hours, which ASIC project generally takes more design hours than FPGA anyway.

I am not in HFT so maybe not the best to answer, but ASICs just wouldn't work for HFT.

Basically FPGAs favour low volume, highly configurable projects. Whereas ASICs favour high volume, very defined projects.

Seeing as HFT algos must change often there would be great benefit in being able to reconfigure FPGA. ASIC you would be stuck with your old HFT algos.

ASIC also are $$$ to produce an initial run, the initial run can also have bad HW bug in it which cannot be fixed and ASIC needs to be respun again, costing more $$$.

It works for Bitcoin, because people lots of small consumers would buy Bitcoin ASIC with simple and non changeable algo and because of the bottom line power usage mattered.

HFT firms I imagine don't care about performance per watt.

doc_holliday··on FPGA Webserver
I would imagine in such a case exploits would be very rare.

It would need to be a very specific exploit and yes there is little scope for what can be exploited as it FPGA is designed for very specific task unlike a general purpose CPU in server.

You would need to have deep knowledge of the HDL to even begin to think up an exploit.

doc_holliday··on New 8-megapixel camera board on sale at $25
Awesome stuff.

I do wish they'd release a module without the bayer filter for monochrome imaging.

Granted it is maybe quite a bit of work to rewrite parts of the ISP to suit a relatively niche market of monochrome sensor...
